Continuing on with hand tools.

The next tool you need to have in your arsenal is a utility knife. Commonly known as Stanley knives, after the company that made them popular, the best knife is one with replaceable good quality blades that are enclosed in a metal cover. I prefer the original Stanley Knife. It has a solid metal cover, a place to store spare blades, and, it can take straight edged blades or hooked edged blades, both of which you will always find useful.
Some people don't like that they need a screwdriver to open the metal casing to replace the blade (or flip it to the unused side). However, I find this is a small inconvenience because the blades do last very long.
If you think you would find this blade change cumbersome, opt for a plastic knife that has 'break-off' blades. I really don't know if there is a technical term for these blades, I have never heard them called anything other than 'break-off' or disposable. The blade is scored in half inch segments and as each segments becomes blunt, you just snap it off.
What ever type of knife you get, buy yourself two or three. Each person working should have their own. And don't skimp on the cost of the replacement blades. The better quality blades can be a bit more expensive but they do last longer and are more stable to use.
I hope you are finding these posts useful. If there is a tool you are not sure about, drop us a line. More to come.
